Step 1: Check your hardware
Make sure your microphone, camera, and speakers are plugged in to your computer and turned on (microphone isn’t muted). If you connect any of your hardware using USB, check if you need to install software from the device manufacturer. Make sure other programs on your computer aren’t using your microphone, camera, or speakers. At the bottom of the video call window, make sure you’ve turned on the microphone or camera .
Step 2: Check your Hangouts settings
At the top/bottom of your video call window, click Settings. Make sure the correct device is selected for each setting (change it using the Down arrow): Camera : If your camera is working, you’ll see your video on the top right. Microphone : To test your microphone, speak out loud and ask if the other person can hear you.
Speakers : To test your speakers, click Test.
If you do not have an external webcam then you do not have to select anything. If you have connected an external headphone then you have to select your headphone in Microphone and speaker option. Showing below should continue with speaker option.
